Given:
Line of the graph
To find:
Equation of the line
Solution:
Take any two points on the graph of the line.
Let the points are (0, 3) and (3, 0).
Slope of the line:
Here,
m = -1
b = y-intercept
y-intercept of the graph is the point which x = 0.
y-intercept is 3 when x = 0.
⇒ b = 3
Equation of a line:
y = mx + b
y = -1(x) + 3
y = -x + 3
The equation of the line is y = -x + 3.
X=hamburgers
y=hotdogs
3y+2x=8.00
AND
2y+3x=8.25
Now we've got a system of equations!
Choose a method to solve it, and I think you'll be good from there.
If you need more guidance to the answer, tell me in the comments.
BEST OF LUCK:)
Answer:
c. Substitute
Step-by-step explanation:
A graph of the function on the left shows the parabola touches the x-axis at x = -8/3. That is, the vertex is on the x-axis. It crosses the y-axis at y = 64.
<h3>Show a value is a root</h3>
A given solution to an equation can be verified by substituting that value into the equation an showing the result is a <em>true statement</em>. Here, the value x=-8/3 is a root of the given equation because that value makes the equation true.
Answer:
24
Step-by-step explanation:
D= diameter of semicircle= 10 ft
Therefore, r= d/2 = 10/2= 5 ft. r^2= 25
And, the formula for area of a semicircle is half that of a circle so,
A/2= [(pie=3.14) x r^2] /2
= [3.14 x 25 ] /2
= 39.25 m
